The balanced chemical reaction is:
<span>2SO2 + O2=2SO3
</span>
We are given the amounts of the reactants to be consumed in the reaction. These amounts are the starting point for the calculations.
5.0 L SO2 ( 1 mol / 22.4 L ) = 0.2232 mol SO2
3.0 L O2 <span> ( 1 mol / 22.4 L ) = 0.1339 mol O2
From the chemical reaction, the mole ratio of the reactants 2:1. Therefore, the limiting reactant is SO2.
</span><span>0.2232 mol SO2 ( 1 mol SO3 / 2 mol SO2) ( 22.4 L / 1 mol ) = 2.4998 L SO3</span>
<span>The chemical equation for the Vinegar & Baking Soda reaction is:
NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)
with s = solid, l = liquid, g = gas, aq = aqueous or in water solution
Another reaction is:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
The chemical reaction actually occurs in two steps.
First, there is double displacement reaction in which acetic acid in vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
Then,Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:
H2CO3 → H2O + CO2</span>

All others are a physical change
Answer:
THE MOLARITY OF SULFURIC ACID SOLUTION IS 0.05 L
Explanation:
Ca Va = Cb Vb
Ca = ?
Va = 75.0mL = 0.075 L
Cb = 0.150 M
Vb = 25.0 mL = 0.025 L
Ca = CbVb/ Va
Ca = 0.150 * 0.025 / 0.075
Ca = 0.00375 / 0.075
Ca = 0.05 M
The molarity is 0.05 L
